I Specification of Letters Patent.

Patented July 23, 1907.

To all whom it may concern:

Be it known that 1, JOHN L. FRUIN, a citizen of the United States, and a resident of Brooklyn borough, New York city, and State of New York, have invented certain new and useful Improvements in Sanitary Ts, of which the following is a specification.

My invention relates to that type of plumbers fitting which is known as a sanitary tee;being a fitting intended to form an integral part of a waste-pipe and provided with an opening through its side by which water or other matter to be carried away by the waste-pipe can be received and with another opening whereby said tee may be vented independently of such venting as would naturally arise from its being a part of the main waste-pipe, which of course serves as a vent, provided the part above said tee is not at the same time acting as a Waste-pipe for something above it.

The object of my invention is to increase the strength and the capacity of these sanitary tees and at the same time to secure the separate or individual venting of the articles to be discharged and vented through the medium of said tee.

For sanitary purposes it is important. as I have found, that where a water-closet bowl, a slop-sink, a bath-tub, and a wash-basin, or any two of these articles are so set as to discharge into the main waste through the same fitting or tee, the odors, gases and other eminations from one should not be allowed to enter the other. Protection to a certain extent is afforded by the traps or water-seals but I have found it desirable to guard, by a proper construction of the sanitary tee itself, against any defect in the seal; and also to avoid the possibility of siphoning-out any of the traps by a temporary choking of the waste-pipe from any cause.

To this end my invention consists in a sanitary tee composed of a straight portion adapted to form a length of the main waste-pipe, a lateral enlargement or body opening out of said straight portion and divided into a number of individual venting passageways and a side opening partly through said enlargement and partly through said straight portion and of sufficient capacity to receive without choking the discharge of one or more closet-bowls and other articles to be discharged and vented; the bottom of said enlargement so tapering into the wall of said straight portion as to afford no lodging place for moisture or other deposit.

In the accompanying drawings, I have shown three somewhat varied forms of my improved sanitary tee.

In Fig. 1, I have shown the simplest form in which neither of the individual vents is tapped within the limit of the tee; it being understood that the tapping is to be done in the connecting pipe leading to said vent. In Fig. 2, one of the vents is tapped within the limits of the tee. In Fig. 3, a projecting hub is provided to serve as an inlet for one of the vents instead of tapping through the side thereof as shown in Fig. 2. i

The difference in the employment of these three forms will be explained hereinafter and other modifications may be introduced if desired; the main features of the invention being retained.

Same letters indicate similar parts in the different figures.

A is the straight portion which is designed to form a length of the main waste-pipe to which it is fitted when in use. This straight portion is preferably hubbed at both ends and should have a bore equal to that of the main waste of which it is intended to become a part.

B, is the lateral enlargement or body portion the underside of which as shown at a has such a taper or sweep into the straight portion A that whatever water or other matter gets into said enlargement falls readily down into and through the main waste.

C is an opening, preferably in the form of a projecting hub which serves as a closet waste. Its diameter is preferably as large as that of the main waste-pipe so that it shall have a discharge capacity as great as the main waste. This projecting hub C is intended to be accessible from the outside of the wall or partition in which the sanitary tee is set and preferably projects slightly into the room from which the closet waste-pipe leads.

The enlargement B is divided at the top into a number of separate vent passages. Two only are shown D, E, but obviously more might be used if desired. These individual passages are separated well down into the interior of the enlargement B by a partition I). The depth to which this partition runs will vary with the level at which the vent passage E is to receive its inlet. The vent pipe D vents the body of the sanitary tee as far as emanations of any kind arising from the discharge of the opening C are concerned and when said opening is not discharging serves as a vent for said opening and all closets or other devices which discharge through the same. The vent E serves as a waste-pipe below the inlet and as a vent-pipe above the inlet for the sink, wash-basin or bath-tub with which the inlet is connected.

Where for any reason the inlet has to be located at a higher level than the top of the tee the vent E only serves as a waste the water and other matter received through said inlet running down the tapering body B into the main waste. Where the height of the bath-tub, basin or sink will permit it, it is preferable to have the inlet within the limit of the sanitary tee itself in which case, as shown in Fig. 2, the inlet is in the form of a proj ecting hub 0 adapted to project into the interior of the room at the side of the closet waste C and enough higher to make the discharge and venting of said inlet independent of the discharge and venting of the closetwaste. Sometimes however, the bath-tub, basin or sink is situated in a ditl'erent room from the closet and at such a distance laterally that an inlet projecting parallel to the closet-waste would not be convenient. In such cases the inlet takes the form shown in Fig. 3 as a horizontal lateral projecting hub (Z, adapted to receive horizontal pipe located in the interior of the wall and 0t suflieient length to bring it opposite the location of a hath-tub, sink or Wash-basin to be discharged and vented.

When set up in use this sanitary tee forms a strong substantial and integral enlargement of the main wastepipe and is sutliciently compact and eapacious to receive and support and to act in cooperation with all the pipes leading to or from it to establish proper sanitation in the operations of discharging and venting the various articles usually employed, such as closets, sinks, bathtubs and wash-basins grouped together on the same floor ot' a building.

A sanitary tee composed of a straight portion adapted to form a length of a main waste-pipe, a inultiplevent lateral enlargement thereof divided into a series 0t indi vidual venting pz sages and tapering downwardly into the wall of said straight portion so as to afford no lodging place for moisture or other deposit, and a projecting huh, partly opening through the side of said enlargement and partly through the wall of the straight portion and of su 1' iicient capacity to receive without choking the discharge of several closet-howls or other articles to be discharged and vented. out of line with the main waste and vent whereby said closets and other articles may he collectively received and individually vented.
